 /**
- * Retrieves contextual links for a path based on registered local tasks.
- *
- * This leverages the menu system to retrieve the first layer of registered
- * local tasks for a given system path. All local tasks of the tab type
- * MENU_CONTEXT_INLINE are taken into account.
- *
- * For example, when considering the following registered local tasks:
- * - node/%node/view (default local task) with no 'context' defined
- * - node/%node/edit with context: MENU_CONTEXT_PAGE | MENU_CONTEXT_INLINE
- * - node/%node/revisions with context: MENU_CONTEXT_PAGE
- * - node/%node/report-as-spam with context: MENU_CONTEXT_INLINE
- *
- * If the path "node/123" is passed to this function, then it will return the
- * links for 'edit' and 'report-as-spam'.
- *
- * @param $module
- *   The name of the implementing module. This is used to prefix the key for
- *   each contextual link, which is transformed into a CSS class during
- *   rendering by theme_links(). For example, if $module is 'block' and the
- *   retrieved local task path argument is 'edit', then the resulting CSS class
- *   will be 'block-edit'.
- * @param $parent_path
- *   The static menu router path of the object to retrieve local tasks for, for
- *   example 'node' or 'admin/structure/block/manage'.
- * @param $args
- *   A list of dynamic path arguments to append to $parent_path to form the
- *   fully-qualified menu router path; for example, array(123) for a certain
- *   node or array('system', 'tools') for a certain block.
- *
- * @return
- *   A list of menu router items that are local tasks for the passed-in path.
- *
- * @see contextual_links_preprocess()
- * @see hook_menu()
